    • 本論文為基於IEEE 802.16e的跨層換手協定研究，藉由整合第二層的802.16e網路，以及第三層的Fast Mobile IPv6換手訊息，達到縮短換手延遲時間的目標。
    論文內容裡，除了簡單解說IEEE 802.16e網路的運作，以及Mobile IPv6和其加速機制Fast Mobile IPv6的運作程序之外，並將更進一步地分析IEEE 802.16e與Fast Mobile IPv6在換手時所交換的封包流程，說明如何運用跨層的方法，將IEEE 802.16e與Fast Mobile IPv6訊息合併在一起。
    在論文的最後，透過軟體方式的模擬，將本論文所提的跨層換手方法與IETF上Heejin Jang等人所提的草稿 ”Mobile IPv6 Fast Handoffs over IEEE 802.16e Networks”進行比較，並分析跨層換手方法在換手延遲時間上表現較優異的原因。

    This paper is a research of cross-layer handoff scheme based on IEEE 802.16e. By combining the handoff message of 802.16e and Fast Mobile IPv6, this scheme can shorten the handoff delay time.
    In the following part of this paper, we simply describe how 802.16e works, and we explain the procedure of Mobile IPv6 and Fast Mobile IPv6. Furthermore, by analyzing the packets that 802.16e and Fast Mobile IPv6 brings out while handoff is processing, we explain how to use the cross-layer architecture to combine those messages from two different layers.
    In the final software simulation, the proposed cross-layer handoff scheme is compared with “Mobile IPv6 Fast Handoffs over IEEE 802.16e Networks” which is a draft on IETF. The results of the simulation show that this cross-layer handoff scheme is better than the draft on IETF in handoff delay time.
